Had a Mack truck with similar noise. The piston was hitting the valves as the caps holding the Conrod had come loose. Was soon after a rebuild. Good luck. Drop some oil and check for metal.
Hi mate mine is doing exactly the same thing. Still haven’t figured it out. Would love to know what you find. I just replaced camshaft rods and lifters and this developed
Yep , the noise can be many things for sure ... but as much as " normal mechanics " ? tend to go straight to the big problem first " big ends " Landrovers have a nice clear history of sh-itting Flex plates and rattling like hell ... I am pulling the gear box and checking that first up ... The engine idles dead smooth and pulls fine , so I am leaving the valve train alone for the moment ... I sure will let everyone know what the hell it was after I find it ...lolol
Good to see your still 'ticking' mate
Good to see you and Kerry are still together in Dunolly.
by the frequency guessing valve stem guide is floating loose on exhaust valve
Check for mushrooming on guide can also cause occasional miss
Hydraulic tappet had the same now fixed 👍🏼👍🏼
Did u ever figure it out
Did you found the issue ? I have the same in my 99

Yep , I found bits of a piston in the oil pan ... it was a broken piston skirt :- (

Sounds like a flex plate to me, was that it?
I wish it had been , but not to be .... it was a broken piston skirt :- (
Manual or auto
